AI Security Review
scanned 1d ago · by lpm-firewall-aiThe post-login redirect deliberately reports the flow source and package version to the publisher’s site without a disclosed opt-out, so this is suspicious runtime telemetry. The inspected OAuth and Search Console requests send credentials and data to Google, and the redirect contains no Google token.
Static reason
One or more suspicious static signals were detected.
Trigger
A user runs the `login` command and completes Google OAuth.
Impact
The publisher’s site receives the login-flow source and package version, along with ordinary browser request metadata; no Google token was observed in that redirect.
Mechanism
After storing tokens locally, the local callback redirects the browser to `www.getpercy.io` with `source=mcp-login` and the package version.
AI rationale
The post-login redirect deliberately reports the flow source and package version to the publisher’s site without a disclosed opt-out, so this is suspicious runtime telemetry. The inspected OAuth and Search Console requests send credentials and data to Google, and the redirect contains no Google token.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- After Google sign-in, the browser is redirected to the publisher’s site with `source=mcp-login` and the package version in the URL.
- The CLI handles login only when invoked with the `login` command; successful authentication triggers the redirect.
- The package sends no Google credentials to Percy in the inspected flow; token exchange and Search Console API requests target Google.
Evidence against
- OAuth uses Google’s authorization and token endpoints, and requests Search Console data from Google.
- The package stores tokens locally in `~/.search-console-mcp/credentials.json`.
- The manifest’s `prepublishOnly` script builds the package; it is not an install hook.
